The UNR9111J0L is a single, pre-biased bipolar junction transistor (BJT) designed to aid in voltage regulation. The device has two distinct operational characteristics: Its regeneration and blocking capabilities. The UNR9111J0L is ideal for use in applications where both high current capability and tight regulation of output voltage are required.

The first operational characteristic of the UNR9111J0L is the ability to act as a regulator. When the device is connected to the power source, it is able to maintain the output voltage with a ±2% margin of error, making it suitable for a wide range of applications, from consumer electronics to automotive and industrial applications.

The second operational characteristic of the UNR9111J0L is its “blocking” capability. This feature enables the device to effectively prevent excessive voltage from being delivered to the load. When the output voltage reaches its maximum safe operating level, the UNR9111J0L will block any additional voltage, ensuring the output voltage remains in a safe range. Moreover, the device features a “dual-active breakdown”, which prevents the device from shorting out under high levels of input voltage.

In addition to its regulatory and blocking capabilities, the UNR9111J0L offers a wide variety of environmental and long-term reliability features. Its monolithic structure provides both high stability and reliability in extreme temperature environments. Its peak overload current is limited to 150 mA, ideal for high-powered requirements, while its maximum quiescent current is 40µA, enabling efficient power consumption. The device is also highly resistant to humidity, oxidation, and electrostatic discharge.

The UNR9111J0L is a versatile and reliable device for voltage regulation and blocking applications. Its ability to maintain tight regulation of output voltage, in addition to its superior protection from overload and extreme temperatures, makes it an excellent choice for a wide range of designs. Moreover, the device’s excellent resistance to oxidation and electrostatic discharge further extends its operational lifetime, ensuring years of reliable performance.
